In the related art, in order to prolong the service life of the multi-story modular house, the upper and lower connecting modules are usually installed in the adjacent upper and lower two-story boxes respectively. When assembling the multi-story modular house, the connecting structures such as steel bars or the long tie rod runs through the upper and lower connection modules between the adjacent two-layer boxes. Finally, the grouting materials are respectively poured between the connection structure and each connection module to form a mechanical occlusion. The grouting materials are concrete, so that the adjacent upper and lower boxes form an effective connection, and make the multi-story modular house have the ability to resist tension and shear. After one box body is hoisted above another box body, it is necessary to use the calibration structure installed on the upper connection module or the lower connection module to calibrate the position between the adjacent two layers of boxes, and then the connection structure pass through the phase and connect the upper and lower connection modules between the adjacent two-layer boxes, and finally the grouting materials are poured between the connection structure and each connection module.

However, it is risky for the assembler to assembly under the hoisted second box 3. Therefore, it is preferable to arrange the first connection module 11 and the connector 13 on the top of the first box 2, which is convenient for installation and can reduce the probability of safety accidents.

Referring to FIG. 1 and FIG. 2 , in another example of the present application, the multi-story modular house includes a plurality of first boxes 2 arranged side by side, and a plurality of second boxes 3 arranged side by side, and the plurality of second boxes 3 are arranged correspondingly. On top of multiple first boxes 2, adjacent first box 2 and second box 3 are connected through connection assembly 1.

In the actual situation, it is flexibly designed according to the actual living needs, so that the plurality of first boxes 2 and the plurality of second boxes 3 can be assembled, which has the advantage of strong functionality.

Referring to FIG. 1 to FIG. 3 , in another example of the present application, the multi-story modular house further includes a fixing part 4, and two adjacent first boxes 2 and two adjacent second boxes 3 are connected through the fixing part 4.

In this example, two adjacent boxes on the left and right can be connected by fixing part 4, so that each box is connected to form an integral structure, so that the overall performance of the multi-story modular house can be improved, and the multi-story modular house can be used in areas prone to severe conditions such as earthquakes or extreme weather.

Further, as shown in FIG. 1 to FIG. 3 , in this example, the fixing part 4 can be a connecting plate with the same structure as the auxiliary connector 15, two adjacent first boxes 2 are connected by a pair of connecting plates, and two adjacent second boxes 3 are also connected by a pair of connecting plates. The connecting plates are connected by a pair of connecting plates, and the connecting plates are arranged at intervals along the vertical direction, so that an integral structure can be formed between the adjacent four boxes.

Further, as shown in FIGS. 1 to 3 , in this example, the connecting plate is a triangular plate, and the two adjacent triangular plates are arranged in opposite directions, which can prevent the eccentricity of the left and right boxes and avoid the connection between the left and right boxes. stability is affected.

Referring to FIG. 5 , FIG. 5 is a partial enlarged view of B in FIG. 3 .

As shown in FIG. 1 , FIG. 3 and FIG. 5 , in another example of the present application, the multi-story modular house includes a plurality of first boxes 2 arranged side by side, and a plurality of second boxes 3 arranged side by side, the multi-story modular house also includes first pad 5 and second pad 6. Two corners of the first box 2 located at the top of the outermost of the multi-story modular house, are provided with first pads 5 respectively. The first pad 5 is specifically arranged between the first connection module 11 at the top of the first box 2 and the connection block 123 at the bottom of the second box 3, and the first pad 5 is provided with a third through hole 7 for the connector 13 to pass through; the adjacent four corners of the first box 2 are provided with two second pad 6, the second pad 6 is horizontally arranged on the top of the two adjacent first boxes 2, and the second pad 6 is specifically arranged in the first box 2. Between the first connection module 11 at the top of the box 2 and the connection block 123 at the bottom of the second box 3, and the second pad 6 is provided with two third through holes 7 for the connector 13 to pass through.

In the actual situation, if the first connection module 11 and the second connection module 12 of the upper and lower cabinets are directly contacted and supported, it is necessary to precisely control the surface accuracy of the first connection module 11 and the second connection module 12 to ensure that the upper and lower cabinets are tilted, which will greatly increase the manufacturing cost. In this example, the first pad 5 and the second pad 6 are arranged on top of each first box 2 to isolate and support each second box 3. During production, it is only necessary to improve the surface precision of first pad 5 and the second pad 6, thereby reducing production cost.

The above descriptions are only preferred examples of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
